Abstract
A method of packaging a food product for retail sale includes forming a bag of sheet material and inserting a food product into the bag. The bag includes a ventilated, reclosable closure arranged to secure the bag against loss of bag contents that has first and second bands of fastener elements placed to form the ventilated, reclosable closure along an opening of the bag. The closure allows an amount of air into and out of the bag with the bag in a closed position after the bag has been opened at the opening to access the food product. The first band of fastener elements is an array of male fastener elements with stems extending from a base and heads arranged to engage a field of fibers.
